CHARLES F. CARE AND GILBERT F. HOLBROOK, OF NORWICH, NEW YORK.

Letters Patent No, 74,890, dated February 25,1868.

IMPROVED BOOT AND SHOE-LAST.-

To ALL WHOM IT MAY couonam Be it known that we, CHARLES F. CARR and GILBERT FLHOLBRQOK, of Norwich, Chenango county, and State of New York, have invented a new and useful Improvement in Boot and Shoe-Lasts; and we here declare that the following is a full, clear, and exact description thereof, referencebeing had to the accompanying drawings, and' 'letters of reference markedthereon, in which- Figure 1 is an 'elevationot' our last, with instep-block ready to be placed in position.

Figure 2, a longitudinal central section; and p Figure 3, a plan of the hook is described. 7

The nature of our invention consists in the improved mode of fastening and'unfastening the instep-block of the, common boot and shoe-last, so that the instep-block can be readily attached or detached at pleasure, by means ofa sliding bolt, which forms a catch, being operated by a coil-spring; also the manner of sliding the bolt or catch, so as to detach the instep-block from the main part of the last.

To enable those skilled in the art to make and use our invention, we will proceed to describe its construction and operation. I

We take the common last, known as the block'last, at right angle with the division of the block or last. We bore a hole in the instep-block, running to and past the hole that is used to remove the block from the last when in tl1e shoe or boot. At the bottonr of the hole we put a suitable coil-spring, a, the object of which is to force the bolt into the main part of the last. In the hole we put a sliding bolt or catch, 5, which is kept in place by suitable stops or bushing, c, which keeps the bolt or catch in its position, and allowing it to slide in and out when desired. In the main part or the bottom of the last is a hole,-d, parallel with the belt or catch in the instep-block. This hole is provided with a suitable bushing, e, and is intended to receive the bolt or catch. At or near the end of the sliding-bolt or catch is a hole,f, for the purpose of unfastening the block froni the last, the hole in the bolt being parallel with the hole in the instep-block. For the purpose of detaching the instep-block from the last, a suitable last-hook, g, is used, with its end tapering, which will enter the instep-block, also the hole in the end of the bolt or catch; the hole in the bolt being about half its size below the hole in the instep-block, so that'the hook entering the holein the instep-block, will enter the hole in the bolt of catch, the bolt will rise up and disengage itself from the last. r V

It will therefore be seen that by placing the instep-block on the last, and pressing it down, so that the bolt COIDC'S lD contact with th hole in the last, the spring at the opposite end of the sliding bolt will be forced into the hole inthelast, and held firmly together. For the purpose of detaching the block from the last, the lastbook is forced into the hole in the instep. lock, and the bolt or catch will be forced out of the hole in the last, and detach the instep-block from the last.

Claim.

What we claim by our invention; and wish to secure by Letters Patent, as new and useful, is The sliding'bolt b, operated on as described and shown, and for the purposes as substantially set forth.

GILBERT F. HOL-BROOK.
